Process Intensification

Modify. Intensify. Amplify.

As biopharmaceutical manufacturers and CDMOs face growing pressure to increase throughput and lower costs in order to stay competitive, process intensification (PI) seems the natural solution – but many feel implementing that level of change is an unrealistic expectation. Sartorius helps manufacturers balance today’s demands with tomorrow’s discoveries, intensifying key processes to experience the benefits of PI now while building for the future.

Sartorius offers various intensified solutions that can be applied to both upstream and downstream unit operations that will result in increased overall productivity of your process or facility. Our technologies, which include high-throughput tools for process development and scalable, flexible manufacturing solutions, combined with our team of expert application scientists, help manufacturers succeed in their PI journey. 

What is the Definition of Process Intensification?

Process intensification is a holistic framework to maximize overall productivity of the unit operation(s), or the manufacturing process, or the facility output for biomanufacturing.

Why Intensify a Bioprocess? 

  • Faster drug development 

  • Achieve up to 4x increase in titers in upstream processing 

  • Increase productivity in downstream by up to 50x  

  • Reduce chromatography resin volume and costs by up to 80% 

  • Applicable to any process irrespective of molecule

Increase Productivity

Producing Diverse Molecules at Various Volumes

For biopharmaceutical manufacturers to stay competitive while delivering multiple specialized products in smaller batches or blockbuster-level volumes, they must achieve the highest levels of productivity possible. Unfortunately, many are operating within existing stainless-steel facilities built for large volumes, and they cannot compete with facilities that employ single-use solutions and other intensified technologies. 

Concentrated Fed-Batch Fuels Productivity

Intensifying seed train operations is one way to see immediate impact on upstream productivity.

Concentrated fed-batch enables manufacturers to achieve productivity levels up to four times that of standard fed-batch operations. Enabling concentrated fed-batch capabilities is one way Sartorius helps bring process intensification technologies into existing systems or when planning new facilities.  

  • The Biostat STR® single-use, perfusion enabled bioreactor manages volumes from 50 L to 2000 L and with integrated analytical and automation tools for PAT.

Reduce Cost of Goods

Manufacturing Complex Products While Controlling Costs

In the past 10 years, the average annual peak sales per molecule has decreased by 50% while average annual costs to develop each molecule increased by 30% – this introduces a mission-critical need to reduce COGS. Manufacturers that currently rely on fed-batch operations have an opportunity to introduce technologies that can quickly modify their existing upstream processes to bring larger gains in productivity and ultimately reduce production costs.

N-1 Supercharges the Seed Train to Bring Costs Down

Implementing N-1 perfusion in the seed train can result in a 30-50% reduction in cost/g compared to standard fed-batch operations and is a key example of process intensification. Sartorius is the only company offering two flexible N-1 seed train intensification options for rocking motion and stirred tank bioreactors along with state-of-the-art integrated analytical tools:

  • The Biostat® RM rocking motion bioreactor with single-use Flexsafe® RM bags, integrated perfusion membrane and in-line analytical & automation tools.
  • The perfusion enabled Biostat STR® single-use bioreactors from 50 L to 2000 L scale with integrated analytical and automation tools ​(additional cell retention device necessary).
  • The 4Cell® XtraCHO media system optimized for CHO-DG44 cells.

Increase Flexibility

Gaining Flexibility in Your Operations

As medicines become more specialized, the number of low-volume batches and variables in manufacturing processes will increase significantly. Analyses of commercial R&D pipelines between now and 2025 indicate more than 80% of candidates would require production of less than 500 kg per year to meet demand. To keep up with these trends, manufacturing operations need to manage higher throughput of individual therapies as well as accommodate different modalities within the same facility.

Intensified Bioprocessing Made Possible with CFB

​Sartorius can help introduce concentrated fed-batch (CFB) technology, enabling manufacturers to achieve throughput 3-4 times higher than standard fed-batch. This supports intensified bioprocessing and the flexibility biomanufacturers require to remain competitive:

  • The Biostat STR® single-use, perfusion enabled bioreactor and the Biostat® RM rocking motion bioreactor with integrated, analytical and automation tools for PAT.

Reduce Footprint

Accommodating a Modular Mindset

Traditional upstream operations that rely on fed-batch processes simply cannot support the diversity of modalities resulting from innovations in protein-based medicines. Meanwhile, specialized medicines mean smaller throughput requirements, with almost 60% of drugs requiring 300 kg/year throughput or less to satisfy patient demands. Given these trends, manufactures are looking for flexible smaller modular Single Use perfusion based facilities to support this diversity in modalities and enable faster changeovers between multiple products.

Perfusion-Based Process for Modular Design​

Manufacturing multiple modalities rely on introducing perfusion-based technologies that require smaller bioreactors which often results in modular facility designs. This results in a smaller footprint, lower upfront capex investment and reduced changeover times due to single-use technology​ implementation​

  • Sartorius offers intensification tools such as the Biostat® RM and Biostat® STR which fit all process types with media handling technologies and integrated, scalable analytical tools for small, single-use modular facilities.

Shorten Timelines

Reducing the Time Demands of Process Development

Speed-to-market is often what determines a product’s competitive position and pricing. Selecting the right process development tools that can reduce your development timelines and establish scalable flexible processes becomes very critical.

Reach IND Submission Sooner With the Right Tools

Sartorius offers several solutions to accelerate IND submission by reducing time spent on process development while integrating PAT for faster process optimization. Easy scale-up to any of the different upstream intensification schemes makes this approach very flexible.

  • Sartorius´ Cellca CHO Expression Platform delivers DNA to RCB within 14 weeks and RCB to MCB in five months. With no media or process optimization required from small to large scale for cell line, media and scalable upstream processes, manufacturers can save up to two months in development.
  • Sartorius’ high throughput Ambr® systems along with PAT integration allow faster process optimization. The Ambr 15 Cell culture system is the smallest single-use bioreactor which can mimic perfusion culture at 15 mL volume to optimize the selection of cell line and media. While Ambr 250 perfusion system is an ideal scale-down process development/characterization system.
